Claims. (Cl. 103--86) This invention relates to liquid elevating devices and has particu1ar reference toa mechanism consisting of a tube spirally arranged around an axis for the purpose of raising water 5 by rotating the apparatus when one end thereof is partially immersed in the liquid to be raised.

The primary object of the invention resides in the provision of a construction which may be adapted to raise water from varying levels by means of an efficient hoist of this character which will be subjected to a relatively small degree of wear.

Another object of the invention is in the provision of a pivoted support for the elevating mechanism whereby the latter may be regulated in its movement for adjusting the depth of the clippers or intakes of the device.

A further object of the invention resides in 2 the provision of a sealing means between the rotating parts and the stationary parts of the device which will tend to reduce the friction ordinarily present in conventional packing boxes and the like.

Broadly, the invention seeks to comprehend the provision of a liquid elevating device of the rotating spiral type which may be adapted to raisewater from varying levels as well as providing in a Water lift of this character a sealing means between the stationary and the rotating parts.

Other objects will become manifest in the following description of the drawings wherein:

Figure 1 is a spiral type liquid elevating device embodying the features of the present invention.

Figure 2 is a plan View of the apparatus illustrated in Figure 1.

Figure 3 is a perspective view of the yolk member which pivotally supports the hoist mechanism on the frame.

Figure 4 is a vertical fragmentary section of the sealing means positioned between the rotating and the stationary parts.

Figure 5 is a vertical sectional view of the cylindrical housing and particularly illustrating the coiled tubing therein.

Figure 6 is an end view of Figure 5 showing the relative positions of the dippers, and Figure '7 is an elevational View of the rotating sealing disc.

Continuing with a more detailed description of the drawings, the numeral 1 generally designates a supporting frame consisting of a pair of braced vertical standards 2 and 3 embedded in,

or otherwise supported by, a concrete base 4. To the top of the frame i there is pivotally mounted at a and b a beam 5 comprised of a pair of spaced longitudinal members 6 and l which are shaped in such a manner that ends of opposite 5 members are directed toward each other and are secured by pins 9 and ill, as shown in Figures 1 and 2.

Intermediate the upper andlower ends of the standards 52 and 3 there is a horizontal yolk member ii comprising an annular support i2 having a pair of opposingly positioned shafts i3 and M extending therefrom. The ends 0 and d of the shafts l3 and Hi are journalled to the standards 2 and 3.

In the construction shown there is a cylindrical housing iii which encloses a pair of tubes it and ii spiraled about an inner cylinder is and are connected at the discharge ends by a Y member l9 which has an integral outlet con- 0 duit 2d concentrically positioned with respect to the axis of the cylinder it. A boss 2! about the conduit 2i) provides a seat for a roller thrust bearing which is enclosed in the annular support it of the yolk member M. About the Y 25 member there is a cone shaped extension 23 of s the housing i5 which engages the boss 2i. Thus, the discharge end of the cylinder i5 is supported for rotation.

The cylinder i8 within the coil of the tubes 16 and fl terminates at the Y member i9 and has a closure 2%. across the end thereof. The other end of the cylinder H3 terminates at the end of. the housing it opposite the cone 23 and is likewise provided with a closure 25. Concentrically positioned through the closures E i and 25 there is secured an axle 26 which extends connecting arm which is pivoted to both the 40 pinand the bearing and thus providing a hinged support between the beam 5 and the axle 26.

Theintake ends or dippers 29 and E5 of the coils iii and H extend beyond the housing i 5 and terminate opposite each other in the manner illustrated in Figures 5 and 6.

A float 31 comprising a pair of buoys 32 and 33 connected by an oscillating rod 36, which in turn is connected to the arm 28, provides a support for raising and lowering'the intakes 29 and 3E3 as the water level of the source rises and falls. Atthe outermost end of the heretofore referred to, conduit 2% there is rigidly fixed a disc 35, as shown in Figures 4 and 7. This disc is con- I centrically positioned over the conduit and may be threaded thereon although other means, such as welding, brazing, and the like, may be employed in securing the disc in place. On each side of the disc 35 there are other discs 36 and 31 which are flanged and threaded together at their peripheries. The disc 31 which is farthest removed from the housing l5 receives a discharge pipe 38, as shown in Figures 1, 2, and 4, and the latter is supported by braces 39 which extend to each side thereof from the annular support l2. The braces 39 contact the stationary disc 3! and thereby lend strength to this support.

About the housing I5 near the cone 23 there is fixed a ring gear which is driven by a spur gear 4! which, in turn, is driven by a motor 42 or other source of power through the medium of a shaft 43. The motor 42, like the discharge pipe 38, is supported by the braces 39.

At the end of the beam 5 opposite the arm 28"there is suspended a weight 44. The latter is pivotally attached to the pin II]. By this arrangement the weight M, which may be of different sizes, may be used to regulate the draft of the float 3| and consequently the depthof the intakes 29 and 30.

. The adjoining faces of the discs 35, 36 and 31 are provided with annular interlocking ribs and grooves 36. Any water reaching these grooves provides a lubricant and also acts as a seal between these parts. By reason of this construction the discs may be fitted together rather loosely since the path of escaping water would be angular and thereby retarded in its outward movement.

In operation the coils i6 and H are rotated and water and air alternately introduced therein. By reason of gravity, the water remains in the bottom of each turn of the coils l6 and III and thereby entraps the air thereinabove.

As the coils l6 and ll revolve the quantities of water and air are progressively carried to the Y member I9 and thence out the discharge 38.

The entrapped air of one coil prevents the water of the other coil from entering therein at junction of Y l9, and thus all air and water are discharged through the pipe 38.

Manifestly, the structure herein shown and described is capable of considerable changes and modifications from time to time by those skilled in the art and such changes and modifications as may be resorted to and which come within the spirit and intent of the invention may also be considered as falling within the scope of the appended claims.

What is claimed is:

1. In a water elevator having a rotatable spiral conveyor and a supporting frame, a beam pivotally mounted on the said frame and hingedly connected to the inlet end of the said conveyor, a counterweight supported by the said beam opposite to the discharge end of the said conveyor, and floats supporting the said inlet end.

2. In a water elevator having a rotatable spiral conveyor and a supporting frame, a beam pivotally mounted on the same frame extending lengthwise of the said conveyor and hingedly connected to one end thereof, counterweights attached to the other end of the said beam, a support for the said conveyor journalled to the said frame, and a float attached to and support,

ing the inlet end of the said conveyor.

3. The combination, in a water elevator, of a supporting frame, a yolk member journalled to the said frame and a bearing supported therein, a housing rotatably supported at one end by the said bearing, a cylinder within the said housing and tubes spiralled therearound, means providing communication for the said tubes through the said bearing, intakes in the said tubes opposite the said bearing, floating means connected to and rotatably supporting the said cylinder, braces attached to the said yolk member and a discharge pipe supported by the 'said braces, sealing means between the said tubes and the said discharge pipe, and means for rotating the said housing. 7

4.
